Description

A kind of improve Litopenaeus vannamei Energy harvesting reduce ammonia nitrogen discharge growth promoter and Application

Technical field

The invention belongs to aquatic feeds technical field.Improve Litopenaeus vannamei Energy harvesting more particularly, to one to subtract The growth promoter of few ammonia nitrogen discharge and application thereof.

Background technology

Litopenaeus vannamei (Litopenaeus vannamei) also known as Penaeus vannamei, call white foot shrimp.Because of it Have that premunition is strong, growth is fast, adapt to the cultivation of Low-salinity waters, delicious meat, relatively low to forage protein requirement, be prone to Carry out the features such as high density intensive culture, it has also become one of three big improved seeds that cultured output is the highest in the world, cultivate warp Ji remarkable benefit.China's cultivation Penaeus vannamei area and yield occupy the first place of prawn culturing always, and its cultivation amount reaches More than the 70% of China's prawn culturing amount.

The developing rapidly of culture fishery in recent decades, fish meal prices goes up, and in breeding process, plant protein source substitutes The utilization rate of fish flour is low, the decomposition of residual bait, excremental generation, body eutrophication, Litopenaeus vannamei under ammonia nitrogen stress is lived Dynamic level is decreased obviously, and food ration reduces, and energy utilization efficiency reduces, and the speed of growth slows down, and limits the strong of Litopenaeus vannamei Kang Shengchang.

Therefore, for reducing after fish flour, fodder energy utilization rate is low and water body ammonia-nitrogen content high, and disease such as takes place frequently at the phenomenon, opens Sending promotion nutrient substance to convert, improve prawn weightening finish, the feed additive reducing ammonia nitrogen discharge protection water body environment just seems Particularly important.There is the growth promoter of a single component application report on Aquatic product, but the growth promoter of existing single composition Action effect is limited.

At present, still the most effectively for improving the minimizing ammonia nitrogen discharge of Litopenaeus vannamei Energy harvesting on domestic and international market The feedstuff additive product of growth-promoting class;Do not have one can improve energy utilization efficiency and nutrient deposition, ammonia nitrogen can be reduced again Discharge improves the prawn additive of cultivation water environment.
